Answer:
0 additive alleles = A0B0C0D0
1 additive allele = A+B0C0D0, A0B+C0D0, A0B0C+D0, A0B0C0D+
2 additive alleles = A+B0C0D+, A+BC+D0, A0B+C+D0, A0B+C0D+, A0B0C+D+, A+B+C0D0
3 additive alleles = A+B+C+D0, A+B+C0D+, A+B0C+D+, A0B+C+D+
4 additive alleles = A+B+C+D+
Cerebellum smoothes and coordinates the movement of skeletal muscle.
True, Chordates are animals in Phylum Chordata.Chordates include all of the vertebrates, in which the notochord develops into a backbone, as well as some invertebrates. Invertebrate chordates include tunicates and lancelets.
Since there are 20 heigh-associated genes and only two of the alleles are identical to both of them, the other genes could have different effects on the development of their bone and muscle cells which can result to the two women having different heights.
